Heater tap Blows ambient air after replacement

[Nick86]

Hi there i have put a new heater tap in and hoses and now it blows ambient temp air. In the old system there was a metal tube thing clamped in from factory i believe as the car has only done 76,000kms and was working fine prior to changing it all apart from a hose leak at the connection to the motor. The hoses feel hollow and empty though would i need to open the nipple on the thermostat? Would there be air in the system by the sounds? What do i need to do/ look out for?

Did you bleed the coolant after you replaced it?

I had bleed it very briefly though. where then it dripped a small amount of coolant out of inlet hose was a little loose. it then used coolant in the reservoir up until recently where it now sits fine. Though the radiator is full when i take the cap off. Would of air gotten back into the system?

Yes you need to open the nipple slightly to bleed it. You gotta bleed it until water pisses out.

Did you have the heater tap fully open when you bleed it?
I drive mine to work tap open bleed when I get to work.
Repeat till no air comes out (3 days)

Do you have the vacuum hose connected to the heater tap?

 

[Nick86]

Yes all hoses are connected

By that do you mean having the heater on in the car full on.Then opening the nipple? And to bleed its just the one on the thermostat or is there another bleeder valve?

That's right you need to have the heater turned on in the cabin to get water flowing through the heater core to flush the air out. Then bleed it with the little nipple on the thermostat as above.
Simple process once you know what to do.
